Abstract

An e-vaping device includes a battery section, an e-vaping tank capable of holding a liquid material, and an adapter connecting the battery section to the e-vaping tank. The adapter includes a heater capable of vaporizing the liquid material, and a wick capable of drawing the liquid material from the e-vaping tank to the heater. The adapter is connected to the e-vaping tank and the power source section via threaded connections. The threaded connections between the adapter and the battery section have threads with a non-standard pitch.

First claim

What is claimed is:

1. An e-vaping device, comprising:
a mouth end insert;
a tank defining a reservoir and an air passage, the reservoir being configured to contain a liquid material;
an adapter containing a heater and wick, the heater in fluid communication with the air passage, the wick in communication with the reservoir and the heater, the heater configured to vaporize the liquid material, the adapter having first and second ends, the first end operationally connected to the tank, the second end including first threads having a non-standard pitch; and
a power section, the power section including,
a power supply, and
second threads at an end of the power section, the second threads being configured to mate with the non-standard pitch of the first threads, and
wherein values of nominal dimensions of the first threads and the second threads, other than the non-standard pitch of the first threads and the second threads, are standard nominal thread dimensions, the standard nominal thread dimensions adhering to international standards organization (ISO) Standard Number 68-1:1998 that correspond with a standard pitch of 0.75 mm, the non-standard pitch for the first threads and the second threads being 0.6 mm.

2. The e-vaping device of claim 1 , wherein a major diameter of the first threads and the second threads are 7.00 mm.

3. The e-vaping device of claim 2 , wherein
the standard nominal thread dimensions of one of the first threads and the second threads include a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.080 mm, a thread height of 0.460 mm, and a tap drill diameter of 6.20 mm, and
the standard nominal thread dimensions of one of the first threads and the second threads include a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.188 mm, a thread height of 0.406 mm, and a tap drill diameter of 6.20 mm.

4. An e-vaping device, comprising:
a mouth end insert;
a tank defining a reservoir and an air passage, the reservoir being configured to contain a liquid material;
an adapter containing a heater and wick, the heater in fluid communication with the air passage, the wick in communication with the reservoir and the heater, the heater configured to vaporize the liquid material; and
the adapter having first and second ends, the first end operationally connected to the tank, the second end including first threads having a non-standard pitch, and
wherein values of nominal dimensions of the first threads, other than the non-standard pitch of the first threads, are standard nominal thread dimensions, the standard nominal thread dimensions adhering to international standards organization (ISO) Standard Number 68-1:1998 that correspond with a standard pitch of 0.75 mm, the non-standard pitch for the first threads being 0.6 mm.

5. The e-vaping device of claim 4 , further comprising:
a power section including a power supply, an end of the power section being connected to the adapter.

6. The e-vaping device of claim 4 , wherein a major diameter of the first threads is 7.00 mm.

7. The e-vaping device of claim 6 , wherein the standard nominal thread dimensions of the first threads include one of,
a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.080 mm, a thread height of 0.460 mm, and a tap drill diameter of 6.20 mm, or
a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.188 mm, a thread height of 0.406 mm, and a tap drill diameter of 6.20 mm.

8. An e-vaping device, comprising:
a power section including,
a first housing,
a power supply in the first housing, and
a first threaded connector on an end of the first housing, the first threaded connector including first threads having a non-standard pitch,
wherein values of nominal dimensions of the first threads, other than the non-standard pitch of the first threads, are standard nominal thread dimensions, the standard nominal thread dimensions adhering to international standards organization (ISO) Standard Number 68-1:1998 that correspond with a standard pitch of 0.75 mm, the non-standard pitch for the first threads being 0.6 mm.

9. The e-vaping device of claim 8 , further comprising:
a tank with a mouth end insert; and
an adapter with a heater and a wick, a first end of the adapter being configured to connect to the tank, a second end of the adapter including second threads being configured to mate with the non-standard pitch of the first threads of the power section.

10. The e-vaping device of claim 9 , wherein the power supply of the power section is configured to be electrically connected to the heater of the adapter if the power section is connected to the adapter.

11. The e-vaping device of claim 8 , further comprising:
a cartridge, the cartridge including,
a second housing,
an inner tube within the second housing,
a reservoir configured to contain a liquid material,
a heater and wick in communication with the reservoir and the inner tube, and

a second threaded connector at an end of the cartridge, the second threaded connector having second threads, the second threads being configured to mate with the non-standard pitch of the first threads of the power section.

12. The e-vaping device of claim 8 , wherein a major diameter of the first threads is 7.00 mm.

13. The e-vaping device of claim 12 , wherein the standard nominal thread dimensions include one of,
a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.080 mm, a thread height of 0.460 mm, and a tap drill diameter of 6.20 mm, or
a root radius of 0.108 mm, a pitch diameter of 6.513 mm, a minor diameter of 6.188 mm, a thread height of 0.406 mm, and a tap drill diameter of 6.20 mm.
